Recombinant Human Interleukin 9 (IL9) is a bioactive protein intended for use in cell culture applications. IL9 is produced by CD4+ helper cells, and has been shown to be a pleiotropic cytokine impacting lymphoid and mast cell lineages. This is the 40 microgram size.

• High purity—no interference from other proteins or contaminants
• High biological activity—more results with less protein
• Proven compatibility—Gibco® proteins bioassayed with Gibco® media

High purity recombinant bioactive protein
Recombinant Human Interleukin 9 (IL9) is one of our more than 250 available Gibco® recombinant proteins. To help ensure Gibco® growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to get a biologically active protein.

High biological activity
In-house activity testing of Gibco® Recombinant Proteins includes cell proliferation, cytotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, and protease assays. Recombinant Human Interleukin 9 (IL9) specific activity is determined by the dose-dependent stimulation of the proliferation of human MO7e cells.

Proven compatibility
Gibco® proteins are bioassayed with Gibco® media. Since 1962, Gibco® has been a consistent provider of high quality media, reagents, and sera for reliable cell culture.
